Moved 'incidence.c' and 'incidence.h' to base/generic/system.
Change system_write_graph to use GraphViz directly, and create PNG output.
Created 'TestSystem' suite in test.py and added test for PNG graph create (no checking performed though so far).
Updated Simulation::write to use the new system_write_graph syntax (no filters any more).
Fixed WITH_GRAPHVIZ flags for graph.c.

updated the makefile stuff to work in the current dir structure.
still lots of problems with the install target and now doing
the evil double link because the directories
system, linear, and solver really are NOT independent.

Fixed build problem on MinGW GCC 3.4.2
Fixed problem with font in IPython console on Windows
Some attempts to fix problems with FILE* support in Python bindings
gfortran is now the preferred FORTRAN compiler.
Comment out failing FILE* tests for the moment.

Removed the 'command line solver' from the Tcl/Tk interface.
Deactivated the 'plot' command in slv_interface.
Eliminated various #include <compiler/*> from the solver.
Added another sample model (which current fails because of problem with non-incident diff vars.

Added getParameter by name in SolverParameters.
Fixed up refences to signal-related header files.
Fixed up various warnings from -pedantic compilation.
Identified an apparent bug with RelationCalcGradient (unsafe version).
Added support for compilation of a standalone C++ program (idatest) in SCons build.

Added scons switch IDA_NEW_ANALYSE for the new code that implements a better DAE analysis procedure.
Minor tidying in list.[ch]
Removed some DIEDIEDIE stuff from analyze.c.
Added 'odeid' to the 'varip' structure in same.
Collapsed a bunch of repetitive stuff with those fancy #defines I like so much.
Flipped some return codes from functions integrator.c to return 0 on success.
Added #include for sensitivity.h in lsode.c.
Catch exceptions from sim.build() in do_integrate() in PyGTK GUI.
Attempted to fix tcl/tk for errors from integrator_analyse as well (not tested).

Several changes to get BinToken compilation active again from PyGTK interface. Still not working but the problems now are in the C layer.
Tidied doc for slvDOF.h
Changed BinTokenSetOptions to saner use of strings -- no more 'taking ownership' of char arrays passed.
Added Compiler.use_binary_compilation option in PyGTK GUI.
Moved all the bintoken stuff out of class Type and into Compiler, where it should be (C++).

Some work on fixing error with test_ascSignal.
Breaking down into smaller test cases.
Removed some debug output from detection of ASC_RESETNEEDED.
Changed all calls 'signal' to 'SIGNAL' macro that includes optional debug output.
Removed 'libasctest.so' (made part of libasctestsuite.so FWIW)
Fixed big in test.c wrt CUEA_ABORT.
Added 'print_stack' and 'Asc_SignalPrintStack' and 'Asc_SignalStackLength'.

Refactored tests into a shared library of tests and a executable of
just the CUnit driver. This will allow the CUnit test suite to be executed via
python unittest as part of the growing Python-based test suite.
Renamed setjmp and longjmp to SETJMP and LONGJMP throughout ASCEND, to allow
some debugging output to be added at each call.

Abstracted the internal integrator calls into a struct IntegratorInternals.
Fixed up compile-time list of integrators.
If IDA is not available, then 'INTEG_IDA' will not be defined.
Added ASC_ASSERT_RANGE for assertions x in [low,high).
Changed calling convention for integrator_get_engines().

Removed BBOXWHINE (replaced with some one-time-only warnings for the moment)
Added ExtMethodDestroyFn to allow 'user_data' associated with external methods to be destroyed.
Implemented the destroy fn through to 'extpy' module.
Added 'name' as an extra parameter in the user_data for extpy, to help with debug msgs.
Moved 'solvernotes' to a file of its own (was part of listnotes.py)
Added 'repaint' to GTK 'tools' menu (for debugging)
Added 'python.h' to top of library, type files (pygtk) to stop silly warnings.
Working on some diagnosing of problems as noted in Simulation::checkInstance.
Removed some old comments from namio.h and others.
Renamed 'blsys' to 'sys' in integrator.c.
Some work on fixing up the J*v function for IDA (not yet complete).
Added new 'destroyfn' parameter (as NULL) to all calls to 'CreateUserFunctionMethod'.

added File->Open everywhere equivalent to File->Read ... to resolve pye request.
At a 1.0 release of tcltk, we should consider getting rid of
the file reads, but not before. existing users have muscle memories
that are not to be toyed with.

Added changes to allow autotools build on ubuntu. There were some wrong assumptions
about file locations that I was able to correct using information in the
tclConfig.sh and tkConfig.sh files. This will need testing on Fedora/Unix/etc.

Fixed up standard paths stuff to use 'INSTALL_ASCDATA' as the place where tcltk/python/models etc
will live. The confusion here came from the fact that I was taking 'INSTALL_SHARE' to be be assumed
to mean 'the location of /usr/share' -- hence the resulting '$INSTALL_SHARE/ascend' that was bothering
Ben. The 'INSTALL_ASCDATA' fixes this, and behaves as he will like, I hope.
Also note that I have switched the default situation in config.h.in to use relative paths by default,
which is the preferred CMU way. SCons builds will default to absolute paths on non-Windows systems.

Ben -- reversing out these changes to Driver.c. These are critical to
the correct working of the RPM. I had expected that you wouldn't be
interested in the stuff except for 'RELATIVE_PATHS' which is your
CMU Way Of Doing Things.

Summary: most of the recent complaints about autotools build fixed,
but the buildbot might find a problem with the scons build/install/rpmbuild.
Details:
configure,Driver.c,utilities/config.h.in:
The choice of INSTALL_DATA as a configure variable name
has been repaired (renamed INSTALL_SHARE); INSTALL_DATA is the unix
canonical name for the program 'install' handling a data file.
Both autotools and scons builds have been updated to reflect this,
in the process correcting the definition from prefix/share to
prefix/share/ascend.
autotools build:
Added --with-quiet option to make the install of already installed and
unchanged files less verbose.
Put in a workaround for the '' problem in tkConfig.sh seen by KC/JP.
Added --datadir support to autotools configure. If you configure
the autotools --datadir=PREFIX/share/ascend you get the same behavior
as the Pye packaging; by default you get the CMU packaging convention instead.
Added utilities/env.c to build.
compiler:
Turned off AWAL in anontype.c.
Noodling away at blackboxes continues...

This fixes the new Driver.c implementation. Now, default values of the environment variables
are specified in the file base/generic/utilities/config.h.in, which should be tooled up with
you configuration process. These default values will be subject to environment substiution,
so that if you set the default ASCENDTK=$ASCENDDIST/TK, that will be expanded *at runtime*.
This is to help with the 'application folder' style of installation off-root.

Fixed the problems for Art/Krishnan/Ben and reverted
the undiscussed install tree change.
If an alternate installed location is to be used, install a shell
script which sets ASCENDTK before invoking ascend, don't just randomly
change the driver code to be something it's not
supposed to be.
